Data visualization designer


Which are the Benefits of Data Visualization?

Data visualization. The word that is a lot more spoken of, however i have a very feeling that numerous people do not have the real definition or real feeling as to what data visualization really is. Or, just what it needs to be. First I will attempt to clarify how it is, and only then may i consider exactly what the direct great things about meaningful data visualization are.- data visualization designer

Although some activities that is viewed as data visualizations are extremely old, most development has happened in days gone by 30-40 years. In that period, in the first organized papers of John Tukey or Edward Tufte, I believe that many scientists and later on IT professionals felt like I felt when first unveiled in such literature. The dominant feeling was that everything fell into place and I asked myself how could I make so many mistakes during my career linked to building reports, graphs etc.

I really believe that the most important mistakes in data visualization are created because those don't pay the specified degree of focus on it; these are certain that they understand what they are doing. Even on commercials from top BI vendors, you can see glossy dashboards packed with colors, 3D bar graphs and 3D transparent pie charts. On the untrained eye that looks great, but that's the main from the problem - it only 'looks' great. However it is informative? Lots of colors for encoding visual information leads to visual noise; on 3D bar graphs you can't read measures correctly, so if you're presented with a 3D transparent pie-chart, just pick any two slices and then try to contemplate which slice is greater and also by simply how much?

I hope that you agree that there are much more to visual presentation of quantities then in order to click a 'convert to graph' button in certain application. Whenever we consult fields of psychology, human visual systems and cognition or gest�lt principles of visual perception, we become conscious of data visualization is one area which needs to be done correctly and, more importantly, it could be learned and taught. Let's emphasize just one single example. There is well-known early stage of visual perception that occurs quickly under the amount of consciousness called preattentive processing. It enables every person being able to detecting a unique set of visual attributes at great speed. The 1st example that springs under consideration may be the very text you read. Only have you count how frequently did the term 'visual' occur in this text, you will need a minimum of 10 or 20 seconds for an answer. But, if every word 'visual' are available in bold style and colored red, recognition is going to be imminent. That'll be because difference in color is going to be preattentively perceived. Other such categories include - for example - position, orientation, size or shape differences.

When a data visualization designer understands such simple principles, the guy can apply them to any report or graph, data analysis or information dashboard. Only then will it give a powerful way to comprehend data. When done properly, data visualization could make us think, compare data, read stories beyond our data, will put data within the right context and consequently help decision-makers to make the right choices.
